Din - 5482 Spline Dimensions Calculator [portable]

The DIN 5482 spline standard, though technically withdrawn and replaced by DIN 5480, remains a critical pillar in global mechanical engineering, particularly within the hydraulics, fluid flow, and automotive sectors. A DIN 5482 spline dimensions calculator is a specialized engineering tool used to derive the complex geometric profiles and inspection data—such as dimensions over pins and tooth thicknesses—required for manufacturing and quality control of these involute joints.

To determine the fit and tolerance for a DIN 5482 spline, an engineer must calculate: The DIN 5482 spline standard , though technically

How to calculate (step-by-step)

  1. Choose module mn and tooth count z based on torque and space.
  2. Compute pitch diameter: dp = mn·z.
  3. Set addendum ha (usually = mn) and dedendum hf (usually = 1.25·mn).
  4. Compute shaft major diameter: d1 = dp + 2·ha.
  5. Compute shaft root diameter: df = d1 − 2·hf.
  6. Select engagement length b according to torque capacity.
  7. Determine hub root diameter and bore from mating and tolerance class.
  8. Check tooth thickness and profile using involute geometry (for CAM/CNC generation use standard involute equations or CAD spline feature).
